According to the wind speed prediction appeared in data acquisition difficulties, so as to the poor forecast accuracy, this paper proposed the history data of near BP-ANN wind short-term forecast model, with emphasis on BP model of input layer and hidden layer parameters are estimated. In the certain scope, enumerated input layer and hidden layer parameters, and use a large number of data simulation,...
Constructing effective and efficient indexes for explosive growing multimedia data is a very challenging problem. To solve the problem, Haghani et al. provide a distributed similarity search method in high dimensions using Locality Sensitive Hashing. However, their method needs to estimate a global parameter on the whole dataset beforehand. It is impractical for a large-scale dynamical dataset. This...
In this paper, we studied the ICT application in university and the importance of cost-effectiveness analysis of ICT Projects. It attempted to summarize a suit of indexes for cost-effectiveness analysis and then studied the input-output data of a university's ICT projects by C2R model and cross-efficiency model in DEA. The results showed the main problems in ICT constructions of that school and the...
